ーニング不良を起こしてしまうという欠点があった。In the cleaning mechanism of the conventional image forming apparatus described above, the waste toner scraped off the surface of the photoreceptor by the cleaning blade is transported to the inner part of the waste toner case using one transporter. In addition, in order to convey the waste toner to the inner part of the waste toner case, this conveyor is designed so that its rotating area is close to the threshold plate provided in the waste I/toner case, and the area from which it rotates is close to the threshold plate provided in the waste toner case. They were placed at a certain distance. Therefore, the conveyance of waste toner near the surface of the photoreceptor is not sufficient, and unconveyed waste toner accumulates, resulting in poor cleaning.
